means for thoroughly-mixing the-fuel and air passing from a c'arbure'tortothe engine softhat the e'fficiency of the engine'willbe greatlwin creased and the consumption of fuel reduced. I

"This invention also consists in certain other features of construction and in the comb'ination and-arrangement bf several parts, to be' hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in theappended claims. v

In describing the invention in detail, reference will be had to the accompanying drawings where-- in like characters denote like or corresponding parts, throughout the several views, and in which:-

Figure 1 is a vertical sectional view through the mixing apparatus. 7 J Figure 2 is a section online 22 of Figure 1. V Figure'3 is a section on line 3-3 of Figure 1. Figure 4 is a fragmentary perspective view. of

the vanes on their supporting rings, these parts the centrally arranged opening 3 in the wall which separates the casings, and .the front cas ing I is formed with a centrally arranged inlet opening 4 surrounded by a flange 5 whiclris adapted to be connected with the outlet of the carbureter (not shown). Front and rear-rings 6 are arranged in the casing I and are concentrio to the opening 4 and these rings support the vanes 1 which are spaced apart and'are preferably set at angles of about 30 degrees to the radius of the fan B which the vanes surround. The blades 8 of this fan are formed. of strips having their inner ends curved=-andfastened to a hub 9 which is connected to the shaft I0 which passes through the casing/2 and through the; boss II carried by the casing 2. Anti-friction bearings I2 for the shaft are arranged in the boss and packing means I3. are also arranged in the boss. A fan C is'arranged in the casing .2 andis similar to the fan B and each fan has a backing disk It in rear of the fan andtowhich the blades, are connectecL The casing 2 is of volute shape. as

shown in Figure 3 so that the circumferential wall of the casing gradually increases in radius from-the hub of the fanC ifromone side of the outlet opening I5 of the casing to the" opposite side thereof andsaid'outlet opening I 5 is-adap'ted to be connected' with the manifold orother inlet part of 'theiengine and the fan C is eccentrically arranged in T the casing and a corrugated lining I 6 contacts theinternal wall of the casing 2' and has its; ends conn'ect'd to the casing as'shown' at "I1 in- FigureBK Af'sleeve i8 is placed on the shaft! ll' between 'thehubs-5 of-the fans and the 1 recessed inner ends of theblades of the fans are as shown at 19 in Figure 1, 1

The shaft can be driven fromany suitable part of the engine, such asthe fan shaft and as it will be seen the mixture of fuel vapor and air passes from the carbureter through the opening in flange 5 and through opening 4 into the first.

casing where it is acted onby the blades of the fan B which forces the mixture past the vanes 1 and against the walls of the casing I and then the mixtureflows around the backing plate. I4,

through the opening 3 into the second casing where it is acted on bythe blades of thesecond fan whichfthrow the mixture against the corrugated lining I5 and from this second casing the mixture passes to the engine, not shown." Thus the mixture is thoroughly agitated and mixed so that its combustible qualities are increased'as all small particles of liquid fuel'are broken up and thoroughly mixed with the'air. The device will deliver the mixture under proper pressure to the engine and the mechanical agitation of the fuel will overcome to a large degreethe cooling or, chilling effect of the vaporization .produced by the-' carbureter. The invention provides a greater efiiciency of the motorand economy in the use of.

the liquid fuel.

It is thought that from the foregoing descripinvention will be readily apparent.

It is to be understood'that changes may be madein the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is: a
